I'm looking for a schematic for a 15 amp DCC booster.

DCC as is Digital Command Control for model railroads.

I can find lots of DCC booster circuits for up to 3 amps; the odd one up to 10 amps, but so far nothing over 10 amps.

Ideally would be a design with a minimum number of parts.

- an H-Bridge that can drive 15 amps or better with low on-resistance and short-circuit protection

- and all the DCC logic done by a microcontroller

- power would be provided by a 24 volt switching power supply.
